Saxon 0f5aaf6cb5 revid & cmd/revid-cli: added InputFPS config.Config field 
The InputFPS field can control rate at which we lex frames from the input source. This has
not been a useful feature until now; we now want to simulate realtime input device using file
input. This requires firstly the Loop mode, and now also realistic input rate.

Saxon 99b931f948 revid & cmd/revid-cli: added loop mode so that input may be restarted after completion 
Loop flag has been added to command line flags and in turn sets the Loop field that has been
added to the config.Config struct. mode variable now also checked to see if value set to
Loop, in which case revid config.Config.Loop = true. Revid.processFrom modified so that
when input source has completed Revid.cfg.Loop is checked and input restarted if true.

Ella Pietraroia c4d809be27 Filter interface take 2 
This branch was made because we were having problems with rebasing the original filter-interface branch. Filter-interface was used to make interface for filters and adding into pipeline made a new file (filter.go) that conatins package Filter. This package has the filter interface, with one filter, NoOp. More filters can be added. The filtering stage was placed inbetween lexing and encoding by changing the LexTo function to have the filter as it's destination and making the destination of the filter to be r.encoders

Saxon fc4e88bce6 fixed bugs causing problems with GeoVision H264 RTMP to youtube streaming. 
Two fixes were involved, firstly, access unit delimeters were used to denote access units and the Write timeout on rtmpSender's ringBuffer was
increased to stop the 'unable to dump old write' errors. Also made some small changes elsewhere that should fix future issues, particular with
MTS output.

function to mjpeg.Lex in the case of an MJPEG InputCodec. Added options parameter to mts.NewEncoder function so that we can change options of the
encoder, namely whether it bases PSI interval on NAL type, or number of frames - in the case of MJPEG we based PSI interval on number of frames.
